FIELD OF THE INVENTION

This invention relates to a display device for game machines, which installed into the game machines including pachinko machines and slot machines.

BACKGROUND OF THE INVENTION

The game machines disclosed in the reference documents 1 and 2 (FIG. 5 to FIG. 7) have a plurality of display devices which are fitted as an unit as the same as the present invention. In this case, as a matter of convenience, electronic display with flat or curved surface, sot machine with mechanical rotating drum, electronic or mechanical display device with rotating plate, electronic or mechanical display device with bar shape or the like are called “indication means”.

The game machines disclosed in the reference documents 1 and 2 (FIG. 5 to FIG. 7) have a plurality of display devices which are fitted as an unit as the same as the present invention. In this case, as a matter of convenience, electronic display with flat or curved surface, sot machine with mechanical rotating drum, electronic or mechanical display device with rotating plate, electronic or mechanical display device with bar shape or the like are called “indication means”.

Therefore, since the plurality of indication means to appeal to the sight of the players for playing the game connect integrally around the movable display body, it makes the movable display body to rotate at the predetermined degrees (90 degrees, for example) by drive force of the drive motor so that it makes to change from the first indication means to the second indication means or from the second indication means to the third indication means as a merit.

Accordingly, the movable display body disclosed in the reference documents is arranged rotatably the display surface of each indication means at the back of the base plate so as to appear selectively through the opening of the base plate of the front member (it means a game frame) of the pachinko machine, for example.

And now, FIG. 26 is a schematic explanation view pointing out the controversial points (the possibility for rotating the movable display body 1) of the prior art. The movable display body 1 of the prior art needs to attach each display surface 2 a, 3 a and 4 a of the first indication means 2, second indication means 3, third indication means 4 through a required space 6 against a glass plate 5 a of the front member 5 of the game machines.

When there is no enough required space 6 between the fixed shaft 7 (center shaft which does not change its position) and glass plate 5 a which are provided at the center portion of the movable display body; and the movable display body 1 is arranged at the back portion of the front member 5 as shown in FIG. 26, the movable display body 1 rotates clockwise at the supporting point of the fixed shaft 7 as shown in the phantom arrow 8 so that the edge of the first indication means 2 hits or contact the glass plate 5 a.

Therefore, in order to solve the problem, when the fixed shaft 7 of the movable display body 1 is held off the glass plate 5 a, each display surface 2 a, 3 a, 4 a of the movable display body 1 gets away from the glass plate 5 a remarkably.

For this problem, it appears prominently in the case that one of the indication means 2, 3, 4 dose not have the measure (width or thickness) corresponding to the radius of the movable display body 1. It means that the movable display body 1 rotates centering on the fixed shaft 7.

So at present it has high hopes of appearance of the display device for game machines that the edge of the chassis does not hit or contact the glass plate although the movable display body with single or plural square-shaped display surfaces of the indication means (LC screen, rectangle or belt-shaped wide display or the like, for example) rotates, and the display surface of the indication means does not get away from the glass plate remarkably before and after it changes.

In addition, it has high hopes of appearance of the display device for game machines that can realize many indication mode with the main parts which are described in the above-mentioned display device.

(1) Environment of Practice of This Invention

FIG. 1 is a schematic explanation view of an example of the embodiment of the present invention. Reference numeral 11 is a pachinko machine having a front member, a display device and he like in FIG. 1. Reference numeral 12 is the front member which is called “game frame”, having an openable frame 13 which can lock, a transparent plate 14 (glass plate, for example) which is provided to the openable frame 13 and a base plate 15, which is formed in the shape of a rectangle, which is provided at the rear part of the transparent plate 14 through a predetermined space.

The display device X for the game machines, as shown in FIGS. 4 and 5 for example, is comprised of a fixed member 31; a movable display body 1 which is provided rotatably at the fixed member 31, capable of indicating the predetermined display surface after the plurality of the display surfaces are switched (it is used as the same numeral in FIG. 26 as a matter of convenience of the explanation); and a belt-shaped movable display body 60 which is provided through a motor shaft and parallel shaft supported pivotably to the fixed member (includes not only the fixed member 31 in this embodiment but also a chassis of the game machine) so as to position in the front of the movable display body 1, indicating after the predetermined display surface is switched after the plurality of other display surfaces make to move in the fixed direction, which is differ from the above-mentioned display surface.

In addition, when the display device X for the game machine in the present invention is installed into the chassis of the pachinko machine 11, each display surface 60 a, 60 b of the belt-shaped movable display body 60 and each display surface 2 a, 3 a of the indication means 2, 3 of the movable display body 1 are shown closely up from the opening 16 formed in the base plate 15 in the forward and backward directions each other.

Specifically, one of the display surfaces 2 a, 3 a of the movable display body and one of the display surfaces 60 a, 60 b of the belt-shaped movable display body 60 are directed to the player so as to overlap.

Furthermore, in the embodiment shown in FIG. 1, the first display surface 60 b with the matrix-shaped symbol display window of the belt-shaped movable display body 60 is shown in the front of the player from the opening 16 of the base plate 15, at the same time the symbol display surface 2 a of the movable display body 1 is shown in the back thereof (Furthermore, as shown in FIG. 20, the second display surface 60 c with the circle-shaped symbol display window and the circle-shaped symbol display surface 3 b are shown also from the opening 16 of the base plate 15 sometimes at the same time. In addition, only the information display surface 60 a for the game is also shown from the opening 16 sometimes).

Moreover, each display surface 2 a, 3 a, 60 a can be switched based on the opening 16 of the base plate 15.

(2) Indication Means, Display Surface, Movable Display Body

The words for the main parts of the present invention are explained here. The words of “indication means 2, 3 and movable display body 1” mean the same as the meaning in the explanation of the paragraph of the background of the invention. Therefore, “indication means” of the present invention includes electronic or mechanical display devices relevant to the games. In addition, the belt-shaped movable display body 60 positioned in front of the movable display body 1 is defined by the display device.

In addition, the display surface of the present invention includes the same or different kind of the display surface without the appearance or function. In other word, when the display surface 2 a of the first indication means 2 changes to the display surface 3 a of the second indication means 3 in the movable display body 1, the content of the display surface 3 a is the same as the content of the display surface 2 a (both displays are the initial screen, rotating drum screen, for example) as well as the different content of the display surface 2 a (for example, the display surface 2 a indicates the rotating drum screen, on the other hand, the display surface 3 a indicates another screen).

In addition, at least one of the indication means 2 and 3 is used to play the game, and another may be used to indicate information for the game. It is not necessary to use all display surfaces as “game stage”. In this embodiment, all display surfaces are used as the game stage, and the plurality of the indication means (independence or separation) are installed into the chassis as one unit (one example). However, the movable display body is provided the plurality of the display surface continuously in the left and right direction by one indication means depending on the embodiment of the present invention.

The display surface 60 a, 60 b of the belt-shaped movable display body 60 are positioned continuously in the right and left directions, and they are divided by the display surface 60 a which indicates information for the content of the game and display surfaces 60 b, 60 c with the symbol display window visually based on the opening 16 of the base plate 15. Therefore, there is no borderline on the display surfaces.

In addition, the movable display body 1 and belt-shaped movable display body 60 can drive independently each by drive force of the drive motors 41, 61 which are arranged independently each at the fixed member 31.

Accordingly, the movable display body 1 is switched from the first indication means 2 to the second indication means 3 or from the second indication means 3 to the first indication means 2 owing to a working piece which reciprocates straightly and the guiding means which moves forward and backward with the working piece alternatively by drive force of the drive motor 41. Thereby, the display surfaces 2 a, 3 a of the plurality of the indication means 2, 3 appears through the opening 16 of the base plate 15 which positions in the back of the transparent plate 14 and belt-shaped movable display body 60 so as to be directed to the player.

On the other hand, the belt-shaped movable display body 60 also moves in a horizontal direction by drive force of the drive motor 61 and can switch the display surfaces 60 a, 60 b alternatively. Furthermore, the switched display surface and one of the display surfaces of the belt-shaped movable display body 60 is directed to the player. At this time, the display surfaces 60 b, 60 c having the single or plural number of the symbol display windows and display surfaces 2 a, 3 a which indicates the symbol, which are positioned behind, are connected as a “bingo line”.

(3) First Embodiment of Movable Display Body 1

The first embodiment of the present invention is described in more detail above referring to the description. The present invention is comprised of the combination of the movable display body 1 and the belt-shaped movable display body which positions in front of the movable display body 1. In other words, it is comprised of one belt-shaped movable display body 60 having the single or plural number of the display surfaces, capable of switching alternatively, and the movable display body 1 which is positioned at the backside of the belt-shaped movable display body, having the plurality of display surfaces, capable of switching alternatively.

FIG. 2 is a front view showing the way in which a display surface is directed to the player. FIG. 3 is a plan view based on FIG. 2.

The structure of the movable display body 1 is explained with reference to FIGS. 4 to 11. As is clear from the figures, the first display surface 2 a first indication means 2 is an outer circumferential surface of a plurality of rotating drums 21 which are arranged in a matrix shape. The symbol, which is not shown in the figure, is provided to the outer circumferential surface thereof continuously.

In this embodiment, the chassis 20 of the movable display body 1 is supported in the fixed member 31 which is formed in the shape of a case, and the first display surface 2 a (the circumferential surface of the revolving drum) is positioned at a surface 31 a of a tip portion of the fixed member 31. The movable display body 1 does not project preferably from the edge part of the chassis 20 (because the belt-shaped movable display body 60 is provided behind the base plate 15). Therefore, when the indication means 2, 3 of the movable display body 1 are switched, the display surfaces 2 a, 3 a of the indication means 2, 3 are provided preferably so they do not get away from the belt-shaped movable display body 60.

The fixed member 31 is defined as the supporting member to the movable display body 1. As shown in FIG. 5, the fixed member 31 of this embodiment is composed of a supporting plate 32, which is formed in the shape of a frame, positioning at an upper side thereof and a supporting plate 33, which is shape of a frame, positioning at a lower side thereof and connecting to the supporting plate 32. The fitted parts 34, which is formed in the shape of a straight (not only straight shape but also curved line in some measure), are formed along the surface 31 a of the tip portion of the fixed member 31 at near side of facing supporting part 32 a, 33 a (upper and lower wall parts in this embodiment) of the supporting plates 32, 33.

The working piece 22 provided at the side of the movable display body 1, which is formed in the shape of a rod, engages with the fitted part 34. The working piece 22 can move from the one edge 34 a to other edge 34 b when the indication means 2, 3 are switched.

In this embodiment, fitted part 34 is a straight shape as shown in FIG. 3 so that the working piece 22 reciprocates into the fitted part 34 by drive force of the drive part 40 which is arranged at the lower portion of the fixed member 31, for example.

Although the fitted part 34 is desirably formed up and down as this embodiment respectively, one fitted part 34 may be formed to the fixed member 31 in consideration of the position of the drive shaft of the drive part 40. In addition, the fitted part 34 may be formed the horizontal guide groove which is not illustrated, besides the elongated level guidance hole in this embodiment. Furthermore, when broad cut part for the working piece is formed from the tip surface of the fixed member 31, the fitted part 34 is not the limited element for the independent claim.

In addition, depending on the design, it is not engaged with the fitted part 34, the working piece 22 can reciprocate straightly trough the interlocking piece (not shown in the figure) which moves horizontally along the inner wall surface of the supporting part 32 a, 33 a by force of the drive part 40, for example. Therefore, the presence or absence of the fitted part 34 is the optional matter of the invention.

Furthermore, the pair of the guided parts 35, which is cut and formed in the shape of a V-letter, is formed at the facing supporting part 32 a, 33 a of the supporting plate 32, 33. In this embodiment, the guided part 35 is formed at the side of the supporting plate 32, 33. These guided parts 35 are formed at the suitable parts of the rear of the fitted part 34 so as to cross the fitted part 34. In this embodiment, the guide piece 23 or guided part 35, which move in concert with the working piece 22 always, of the movable display body 1 engages with the fitted part 34. In this embodiment, a plurality of the guide pieces 23 projects from the part adjacent the movable display body 1.

And now, the front edge 35 a of the guided part 35 may be formed in the shape of an arced groove, a curved fitting groove and the like. In this embodiment, a small projecting piece 36, which is formed in he shape of a V-letter, is provided in the guided part 35, defining by a part of the supporting part 32 a, 33 a. The small project piece 36 is formed the right and left guided part 35 b, 35 c at near side, and the movable guide piece 23 a, 23 b engage with the guided part 35 b, 35 c.

The guided part 35 has a function for controlling the rotation range of the movable display body 1, and the right and left guide pieces 23 (23 a, 23 b) move forward and backward in the guided parts 35 b, 35 c when the indication means 2, 3 are changed and move forward and backward in the crossing direction to the excursion of the working piece. In addition, the right and left guide pieces 23 can change the stop position to the front edge 35 a of the guided part 35 as described below (see FIG. 11).

In addition, since the guided part 35 on the female side engages with the guide piece 23 on the male side of the movable display body 1, it's a matter of course that the guided part of the fixed member is defined by the guide piece on the male side when the design of the movable display body 1 is changed to the guided part 35 on the female side.

And now, the guided part 35 has a function for controlling the rotating range of the movable display body 1, and the right and left guide pieces 23 (23 a, 23 b) move forward and backward in the guided parts 35 b, 35 c when the indication means 2, 3 are changed and move forward and backward in the crossing direction to the excursion of the working piece. In addition, the right and left guide pieces 23 can change the stop position to the front edge 35 a of the guided part 35 as described below.

Now the function of the working piece 22 and guide piece 23 are explained. The working piece 22 has a function to pull the movable display body 1 from the one edge of the fixed member 31 to another edge thereof, and the guide pieces 23 a, 23 b have a function to control the rotation range of the movable display body so as to direct each display surface 2 a, 3 a of the movable display body 1 to the transparent plate 14 and each display surface 60 a, 60 b, 60 c of the belt-shaped movable display body 60.

(4) Chassis 20 of Movable Display Body and Indication Means 2, 3, 4

Secondary, examples of the chassis 20 of the movable display body 1 and the indication means 2, 3, 4 are explained. The chassis 20 of the movable display body 1 faces to the inner wall surface of the supporting part 32 a, 33 a of the fixed member 31. In addition, edge parts of an upper wall part 25 and lower wall part 26 of the chassis 20 are formed in the shape of a break or an arc. In this embodiment, each edge is cut to the vertical direction as shown in FIG. 7.

In consideration of the design and function, the appearance of the chassis 20 is formed as “axis of composition of a triangle” so as to able to look like a triangle with long three edges. Moreover, one opening part 27 and other opening part 28 which intersects the opening part 27 have desirably the same size approximately.

Furthermore, in this embodiment, the rotating-drum-shaped first indication means 2 with display surface 2 a in the curved surface shape is installed into one of opening parts 27, and the second indication means 3, which is formed in the shape of a revolving plate, with the display surface 3 a, rotating by drive force of the drive motor 17 is installed into another opening part 28.

In addition, it is not limited element in the present invention, however, the oblong indication means 4 (third stage) with an arced display surface 4 a and upper and lower fan-shaped end faces is installed into a part 20 a (cutting portion of the edge) positioned between the first indication means 2 (first stage) and second indication means 3 (second stage). Therefore, depending on the design, the oblong indication means can be installed into the cut part 20 a of other edge of the chassis 20.

And now, when the case-shaped chassis 24 is formed as a shaft structures the triangle, the above-mentioned upper wall 25 and lower wall part 26 is not always have to form broad plate in whole. For example, although the third frame body is assembled so as to project an image of plan triangle with the first frame body of the first indication means 2 and second frame body of the second indication means 3 and constructs the case-shaped chassis 24 without regard to the device for the indication means, he shaft on the design is the same.

In addition, although the edge of the opening part 27 is formed in the shape of a curve in some measure, not straight line (his embodiment), the basic structure is the same when the display surface 2 a, 3 a of the first indication means 2 and second indication means 3 can be formed.

Furthermore, it is not limited element in the present invention, however, a plurality of sliding member 29 (ball wheels, for example) are provided at the suitable parts of the movable display body 1 so a to rotate the movable display body 1 smoothly.

The movable display body 1 in this embodiment is switched alternatively through the working piece 22 which can reciprocate and guide pieces 23 of the side of the movable display body, working with the working piece 22 with engaging with the guided part 35 of the fixed member 31 by drive force of the drive motor of the drive part 40 which is arranged at the fixed member 31. Such switching may be repeated.

(5) Drive Part 40 For Movable Display Body

The drive part 40 for the movable display body 1 has a relation with the purpose of invention that it switches the indication means automatically into the game so that it is the limited element in the present invention. Therefore, one example of the drive part 40 is explained with reference to FIGS. 4 to 6.

Reference numeral 41 is a drive motor which is arranged at the lower part of the fixed member 31 through the attachment plate; reference numeral 42 is a drive shaft, which is formed in the shape of a screwed rod, connecting to the output shaft of the drive motor; reference numeral 43 is a screwing body, which is formed in the shape of a sleeve, screwing the drive shaft; and reference numeral 22 is a vertical working piece, a lower end part thereof fixing to the screwing body, engaging with the upper and lower fitted part 34 of the fixed member 31 at the passing-through state and passing through the chassis 20 of the movable display body 1. It is not necessary to be passed through the movable display body 1, depending on the design. For example, it may engage freely with an engaging groove which is formed at the chassis 20.

(6) Detection Means For Movable Display Body

The first and second detection means 45 and 46 to detect the rotation position of the movable display body 1 are arranged at the predetermined position of the drive part 40. In other word, reference numeral 45 is defined the left first detection means (sensor) to the index 47 which is provided at the lower part of the screwing body 43, on the other hand, reference numeral 46 is a second detection means (sensor) positioned at the right side.

The detection means 45, 46 are attached to the fixed member 31 through the attachment plate. The detection means 45, 46 using a principal of a hall IC, a combination of light emitting element and light-sensitive element or the like is applied selectively.

(7) Power Supply Circuit For Drive Part

The power supply circuit 50 is explained with reference to FIG. 12. The power supply circuit 50 includes an electric power supply, a control part 51 which controls the drive motor 41 by electric current from the electric power supply, the detection means 45, 46 which detect the rotation-position angle of the drive motor 41.

Since the control part 51 is enough to control order and operation (activation, stop) to the drive motor 41 for the movable display body 1 and a drive motor 61 for the belt-shaped movable display body 60, it does not include the control part, drive motor or the like and means commercial power supply, chargeable battery, pressor circuit and the like which are not illustrated when the power supply circuit 50 is defined narrowly. In the present invention, the composition of the power supply circuit is not limited.

In FIG. 7, reference numeral 51 is a control part (micro computer) installed into the game machines 11 or display device X; reference numeral 49 is an AC power supply; reference numeral 52 is a filing device; reference numeral 53 is a switching circuit, reference numeral is a drive motor; numeral 45 is a first detection means; numeral 46 is a second detection means; reference letter a is a detected signal that the detection means 45, 46 are detected the position (rotating position of the movable display body 1) of the index or magnet 47 of the screwing body 43; and reference numeral 61 is the drive motor 61 for the belt-shaped movable display body 60 and the like. In addition, means 71, 72 for indicating the belt-shaped movable display body 60 are omitted (see FIG. 16).

(8) Changing Display Surface

The automatic switching of the indication means 2, 3 is explained with reference to FIGS. 8 to 11. FIG. 8(a) is a view showing the way in which the display surface 2 a of the first indication means 2 is directed to the player. FIG. 8(b) is a view showing the way in which the working piece 22 is positioned at a left side of the fitted part 34. When the working piece 22 is positioned at an initial state, as shown in FIG. 11, the first guide piece 23 a inside the guided part 35 is positioned with engaging with the front edge part 35 a, on the other hand, the second guide piece 23 b is positioned behind the first guide piece 23 a.

Now the slot machine using the symbols in the first indication means 2 is operated, and the drive motor 41 starts when the predetermined condition is clear in FIG. 8.

The horizontal drive shaft 42 rotates when the drive motor 41 starts so that the horizontal screwing body 43 starts to move from the first detection means 45 to the second detection means 46 as shown by the arrow. Therefore, the signal output part 47 of the screwing body 43 moves from the first detection means 45 to the direction of the second detection means 46. Then the screwing body 43 moves, and the working piece 22 moves straightly on the fitted part 34.

In addition, the feature of the game of the filing device which is not the limited element for this invention can also be set up arbitrarily and can be adopted.

(e) The drive shaft for the movable display body formed in the shape of a screwed rod and the screwing body which screws to the drive shaft and move straightly are used in order to simplify the structure of the drive part.

The belt system, gear system, crank system and the other methods may be used for transfer of drive force of the drive part, and it is not limited especially. Moreover, also it is the same as the transfer of the drive force of the drive part of the belt-shaped movable display body. Moreover, the arranging part is not limited.

(f) In addition, the index or magnet for the detection means provided to the screwing body is not limited the description in the embodiment especially. Moreover, the hall element 45, 46 are attached to the attachment pieces for the sensor which are attached to the right and left portions of the fixed member 31 when the magnet 47 is fixed directly or indirectly to the suitable portion of the outer circumferential part of the screwing body 43. If this is the case, the detection means detects the magnetic flux of an N pole of the magnet 47 and outputs the positioning signal of the screwing body 43 to the control part 51 when the screwing body 43 moves horizontally and faces the hall elements 45, 46. Moreover, also it is the same as the detecting means 71, 72 of the belt-shaped movable display body.

(g) The movable body 1 in the embodiment rotates horizontally. However, it may be installed into the fixed member 31 so as to rotate vertically. In addition, the guidance (engaging) relationship between the guide piece 23 of the side of the movable display body and guided part 35 provided at the fixed member 31 may be set the opposite mode. In other words, however it is not illustrated, the guided part 35 is provided at the side of the movable display body 1, on the other hand, the guide piece 23 may be attached to the fixed member 31. This is also the embodiment of the present invention.

Moreover, although one guided part 35 is formed at the upper and lower walls 25, 26 of the fixed member 31 in the embodiment, the second guided part may be formed in the crossing direction to the guided part 35. If this is the case, the plurality of indication means installed into the movable display body can be switched voluntarily, and as a result, the effect for the replacement of the new device can be brought out.

(h) In the embodiment, it is arranged to the front member of the pachinko machine 11. Also it may be used in the display device X1 for slot machines, other game machines. FIG. 25 shows the example showing the way in which the display device X1 of the present invention is provided at the back (inside the chassis) of the front member 12 in the slot machine 11A. For this example, the display device X1 is used as a sub game, and the display device X1 is used as the display device for the main game by itself. Therefore, it is possible to use in many ways.

(i) Although the display window f or symbol of the display surface 60 b of the belt-shaped movable display body 60 is divided by nine partitions, the number of the partitions corresponds to the number of the first indication means 2 of the movable display body. Therefore, when the three symbol display surfaces 2 a of the first indication means 2 stand in line horizontally, the display window for symbol of display surface 60 b of the belt-shaped movable display body 60 (60A) is also divided by three partitions with frame line, opening and the like although it is not illustrated especially. Therefore, the forehand display window for symbol has the single or plural number.

(j) In addition, the belt-shaped movable display body 60 moves horizontally since the motor shaft 62 and parallel shaft 63 are provided vertically. However, the moving direction is not limited. In other words, the motor shaft 62 and parallel shaft 63 may be provided horizontally along the upper supporting plate 32 and lower supporting plate 33. In this case, the belt-shaped movable display body 60 moves in the vertical direction.

As set forth above, the advantages of the invention are as follows:

(1) The display surfaces of two kinds of the indication means (“movable display body” and “belt-shaped movable display body”) can be related each other (forward and backward display surfaces are directed to the player) so that it can realize many indication modes.

(2) For the mechanism to make to rotate the movable display body, the working piece which can reciprocate and guide piece or guided part which moves in concert. In addition, for the mechanism to make to move the belt-shaped movable display body in the right and left directions, the motor shaft and parallel shaft which are supported pivotably to the fixed member (including the chassis of the game machine) are used. Therefore, it can achieve the main purpose of the present invention by easy and rational mechanism.

(3) Since one of the indication means is defined by the belt-shaped movable display body which moves by means for rolling up (motor shaft, parallel shaft), it can be arranged at a space between the backside of the base plate of the front member of the game machines and the belt-shaped movable display body.

(4) Since the movable display body is not used the fixed shaft in the traditional way, each display surface of the indication means does not get away from the transparent plate of the front member of the game machine although the movable display body rotates. Specifically, it does not get away from the belt-shaped movable display body although the indication means of the movable display body is switched alternatively.

(5) When the display device of the game machines is exchanged to other device (it changes for a new device), it can achieve the exchanging effect of a new device easily only by switching one indication means of the movable display body to other indication means by drive force of the drive motor or manual operation.
